.and it is important that the arrangement 4be such that the two men incooperation can readily and easily apply and tighten the bars inapproximately their final adjusted posi` tion. It is likewise importantthat the bars be capable of ready adjustment later by one workman or bytwoworkmen at they most to their final adjusted position for supportingthe courses of stone or brick to be carried thereby in accuratelyadjusted position with respect to thefother courses adjacent thereto. Itis also important that the hangersl be of such an arrangement that theycan be tightened properly without danger of breakage and that thehangers when tightened shall have a substantially positive grippingeffect on the angle bars of such strength as to be effective withoutmaterial danger of failure.

It is the object of my invention to, provide a construction ofthis typehaving the several desirable features above outlined, so that the anglebars can be placed quickly and easily in the desired adjusted positionand that the facing portions of the wall shall be securely and safelysupported thereon. It is another object of my invent-ion to improvedevices of this type in sundry details hereinafter pointed out. Thepreferred means by which I have accomplished my several objects areillustrated in the drawing and are hereinafter specifically described.What I desire to cover by Letters Patent is set forth in the claims.

In the drawing,-

Fig. 3 is a vertical cross section through my improved insert box of thetype preferably used in connection with a concrete wall structure, andshowing in dotted lines a changed position of the securing bolt.

Fig. 4 is a face view of the box of Fig. 3.

Fig. 5 is a View similar to a portion of Fig.

3, but showing a modifiedy form of construction.

Fig. 6 is a 'face View of a modified form of" insert box.

Fig. 7 is a vertical cross section through an 'I-beam forming a part 'ofthe frameworkof a steel building and having my improved anchor devicemounted thereon; and

Fig. 8 is alview similar to Fig. 7 but showing a modified arrangementand including a box for Iprotecting the bolt and its associated parsfrom the concrete to be placed about the stee f Referring nowparticularly to Figsiil to 4 inclusive, 15 indicates a concrete wallhaving been molded between forms 16 of any suitable type and provided atintervals therealong with insert boxes 17 embodied in the wall foryadjustably holding in position securing bolts 18 by which an angle bar19 is adjustably secured in position for supporting the facing portionof thewall. As the art7 it is dicult to curately in position so that aplurality of the boxes may be in perfect alignment in the iinished andhardened wall, wherefore it is necesy sary or important that the boxesbe provided with adjustable means for supporting the bolts 18so that thebolts may be placed in the desired alignment regardless of thev slightdiscrepancies in the positionof the boxes. .It is also important thatthe entire set of'bolts 18y for one of the angle bars 19 be adjustablesimilarly up and down so thatthe bar 19 can be placedL accurately inposition with 'respect to is well understood in place the boxes 17kacthe facing portion of the wall below regardf f less of slightvariations in the position of such facing portions so that the bar 19can sup,-

port the knext higher course of stone or brick in the desiredrelationship to `the courses below. The'vertical adjustment of the bolts18 j with respect to the boxes is effected in `the manner hereinafterdescribed, while the horif zontal ladjustment is ksecured by the provi-`sion of horizontally disposed slots 20 for the bolts18 in the verticallyextending Aportion ofy the bar 19.

The insert boxesy 17 in the `embodiment L shown in Figs. 1 to 4: are inthe form ofk castings comprising side walls 21, a top wall 22 and abottom wall 23, with a back wall 24 formed integrally with ythe otherwalls and i comprising an outwardly ,extending flange 25 about theentire periphery of thefbox. ,In

` the construction shownthe side walls 21 conj verge downwardly withrespect to each other so as to 'providea vertical support for'the boxwithin the concrete wall even though the bottom face of the box is flushwith thebot-y tom edge face of the wall, as is sometimes the case. Bythe provisionvof the flange 25, the

box is secured very strongly in position withV respect to a forward pullupon the box by which the box might otherwisebe drawn for wardly out ofposition within the wall.

In thefconstruction f shown, the front wall portion of the box is in theform of a wedge indicated by the numeral 26, having its front :n andrear faces diverging slightly downwardly, the front face of thewedge4member being adaptedl to conform to the vertical position ofthe rearfaceof the bar 119 Jwhile the rear face of the wedge member divergesdown-k l Iwardly toa slight 4degree with respect to the rear face ofthebar 19. r1he side edges of the wedge member 26 merge 1 withk the sidewalls 21.0f the box throughout the full thickness of the wedge so as toprovide the desired support for the wedge memberwith respect to theouter face of the form 16.

box.

In forming the-wall 15, a plurality of the boxes 17Yare secured inposition upon the form 16`with-the front faces of the boxes' iin contactwiththe form, kthe boxes being.

very firmly secured in position upon the form by the use 'fof heavynails 27 vextending through openings 27a through the box, such nailsbeing preferably Yclinched upon vthe :Forv assisting rangement beingsuch that the head -portioriDs of the bolts can beientered through theVenlarged lportions of`the T-slots after the boxes are'in position. IntheI form shown in Figs. `1to 4, the bolts 18 are standard.vbolts'having square ',heads, being provided with auxiliary headmembers 29'in the form of iheavy washers. In the construction hereshown, the head members 29 `are cut away at opposite sides'so as toprovide lugs 3() at oppo Ysite :sides of the bolt' for engagement in theslots 28 for holding thewashers againstrotation, thevwashers being cutdiagonally so as Vto provide extended bearing faces for the bolts at anangle conforming tothe inclination of the rear faces lof thewedgemembers 26. The

washers 29'; are provided inthe construction shown with `lugs 31engaging the heads of the u bolts 18 :for holding the bolts againstrotation 'when a is desired 'C0-apply an angie bar 19 in position,twoworkmenl handle the opposite ends of the bari for inserting the boltsof the end-boxes 17 through the slots 20 at the ends of thebar, the nutson the bolts 18 being screwed up sufliciently for holding the barloosely in position. The bolts 18 of the intermediate boxes 17 vare theninserted through the corresponding intermediate slots 20 of the bar 19and the nuts are threaded upon their outer ends. kFor enabling theintermediate bolts 18 to be inserted readily through their slots 20,,itis importantthat the bolts be capable of retraction almost completelyinto the boxes,f as shown by the dotted line position of the bolt inFig. 3, the box 17 being formed of a size toenable such manipulation ofthe parts. When the bar 19 is to be tightened into position., the endsof the bar are placed at the desired height and the nuts on the end'bolts are tightened into position. Aswill be readily seen, when it isdesired to adjust the bar 19 vertically after all of the bolts 18are inposition through the slots 20, this can be accomplished readily byvertical movement of the ends of the bar in unison or by an adjustmentofl either end of the bar by itself, the intermediate bolts 18 beingadapted to move without-resistance either upwardly or downwardly alongthe slots 28 of the intermediate boxes. When the bar has been tightenedinto position at its ends, the intermediate bolts 18 are also tightened,and all of the bolts, so far as is necessary or advisable,

are cut oif so as notto interfere with the courses of brick or stone.

As will be readily understood, when one of the bolts 18 is tightened inposition by the nut on the outer face of the bar 19, the bar is heldpositively against downward movement, inasmuch as such downward movementwould necessitate a greater length of bolt. The inclination of the rearface of the wedge member 26 is so slight that at lthe same time the bar19 is held very strongly by friction against upward movement withrespect to the wedge member 26, the frictional engagement between thehead portion of the bolt and the rear face of the wedge being very greatby reason of the fact that the head portion is beveledto correspond withthe angle of the wedge. By reason of the very slight taper of the wedgemember 26, the distance between the rear face of the wedge at the bottomof the box and the front face of the bar 19 is kept within practicallimits so that the support for the bolt 18 shall be kept adequate evenwhen the bolt is-adj usted to its lowermost position in the slot 28. y

In Fig. 5,1 have shown a modified form comprising a` bolt 32 having itshead 33 cut away aty the sides to conform to the slant of the wedge 26and for holding the bolt against rotation with respect to the wedgewithout the use of an auxiliary head member or washer 29. In cases wherea bolt of the type shown in Fig. 5 can be obtained to advantage, thisconstruction is to be preferred to the construction illustrated in Fig.3. The operation of the two devices is substantially the same.

In Fig. I have shown a modified form of insert box in which the sidewalls 34 parallel instead of beingconvergent downwardly as in Fig. 4.'Io compensate for this change so as to provide the desired verticalsupport, I have provided laterally projecting ribs 35 extending acrossthe side walls 34 in spaced relation to the lower end of the box, in theconstruction shown the ribs 35 being placed at the top of the box.Inasmuch as the construction is otherwise substantially in accordancewith that above described, it is believed to be unnecessary to describethe same herein, the operationbeing substantially as above described.

In Fig. I have shown my improved an choring means applied directly tothe fabri# cated steel frame of a building. In this construction, anangle 36 is riveted to the web ot' an I-beam 37 of the framework, with asecond .angle 38 riveted thereto. The angle 38 is provided with aIvertically disposed slot 39 corresponding to the slot 28 of theconstruction shown in Fig. 4. A wedge member 40, preferably in the formof a casting or a stampl` ing and having its rear face divergingdownwardly with respect to its front face which is defined by the edgesot the llange portions, is secured by means of a rivet or other form ofbolt 4l upon the angle 38, the wedge member 40 being provided with aslot 42 corre* spending in shape, size and position with the slot 39. Aplurality of such supporting parts are provided along the I-beam 37 oralong other parts in the desired alignment for sup* porting an angle bar43 by means ot bolts 44, the bolts 44 in the construction illustrated inF ig. 7 corresponding with the bolts 32 of Fig. 5 rather than with theconstruction shown in Fig. 3. Inasmuch as the operation of the partshere described corresponds exactly with that above described inconnection with Figs.

' l to 4, it is believed to be unnecessary to describe it further.

In F 8, the construction is the same as that shown in Fig. 7, exceptthat the slot 45 is formed directly in the web of the beam 46 of theframe work of the building, the beam 46 being shown as a channel beamrather than an I-beam. In the construction shown in F i g. 8, the anglebar 47 is also shown with its outwardly extending flange at the toprather than at the bottom as in the remaining ligures. The bolt 44 andwedge member 40 are also enclosed at the rear tace of the beam 46 bymeans of a sheet metal casing 48 preferably secured in position bywelding for protecting the parts from the concrete by which the rearface of the beam is to be inelosed.

While I prefer to employ the construction as illustrated in my drawingand as above described., it will be understood that I do not wish tolimit my invention to the use of the features there illustra-ted exceptasthe claims are hereinafter specifically so limited, since it will beunderstood that changes may well be made in the construction withoutdeparting from the spirit of my invention.
